Buffalo Bore 10mm Ammo

Buffalo Bore 10mm ammo is built for the backcountry — the brand serious outdoorsmen reach for when a 10mm is their bear-country sidearm. Buffalo Bore specializes in full-power, heavy-bullet loads, and its hard-cast 10mm offerings are designed around one mission: deep, reliable penetration on large, dangerous animals. When the 10mm is your insurance against a bad encounter on the trail, the load matters as much as the gun, and Buffalo Bore is purpose-built for exactly that. It’s part of our full 10mm ammo selection.

Built for Penetration

Against heavy game and predators, penetration is everything — a bullet has to drive deep and straight through bone and muscle to reach vitals. Buffalo Bore’s hard-cast 10mm loads use heavy flat-nose lead bullets (commonly around 220 grains) at full velocity, designed to penetrate far deeper than expanding hollow points. That’s a deliberate trade: hard-cast bullets don’t expand, but they bore straight and deep, which is precisely what bear defense demands. The brand loads to full 10mm pressure, not the downloaded levels common in mainstream ammo.

Buffalo Bore vs. Standard 10mm

Like other full-power specialists, Buffalo Bore loads the 10mm to its true potential rather than the softened “FBI-lite” level many factory loads use. The result is significantly more energy and penetration — and more recoil, which is the cost of that performance. For trail and bear defense this trade is worth it; for range practice, affordable FMJ from a value brand makes more sense. Many 10mm owners keep both: cheap practice ammo and Buffalo Bore for the woods. Our Buffalo Bore 10mm guide covers the lineup.

Who It’s For

Buffalo Bore is for the hiker, hunter, fisherman, or guide who carries a 10mm in country where large animals are a real concern, and for handgun hunters who want maximum penetration. Practice with full-power loads before relying on them — the recoil is real in a Glock 20 or 1911. For larger or more dangerous game, revolver cartridges like the .44 Magnum step up further. Standards follow SAAMI specifications, and full-power loads are also available from Underwood.

Buying Buffalo Bore 10mm

Confirm your chosen load feeds and shoots to point of aim in your pistol before carrying it afield. Federal law sets the minimum age for handgun ammunition at 21; some states and cities add restrictions, so per ATF guidance, confirm federal rules and review our ammunition shipping rules and state restrictions before ordering.

Buffalo Bore 10mm Ammo — Frequently Asked Questions

Would a 10mm stop a grizzly bear?

A full-power hard-cast 10mm is considered a viable, if minimum, bear-defense option, which is why many in bear country carry it — heavy hard-cast loads from Buffalo Bore are designed for the deep penetration that matters most. That said, larger cartridges offer more margin, and shot placement under stress is critical. The 10mm’s advantage is a higher-capacity, more shootable platform than a large-bore revolver.

What is the best 10mm ammunition for bear defense?

For bear defense, heavy hard-cast loads around 200-220 grains at full power are the standard choice, prioritizing deep, straight-line penetration over expansion. Buffalo Bore and other full-power specialists build exactly this. The “best” load is a full-power hard-cast bullet that feeds reliably in your specific pistol — test it before carrying it in the backcountry.

What are the downsides of a 10mm?

The main trade-offs are recoil and ammo variability. Full-power 10mm recoils sharply, which some shooters find hard to manage for fast follow-ups, and factory loads range from full-power to downloaded “FBI-lite” levels, so performance varies widely by brand. Pistols and magazine capacity are also more limited than 9mm. For those who want its power, though, the 10mm delivers.

Why is hard-cast ammo used for bear instead of hollow points?

Hollow points expand, which limits penetration — a problem against the heavy bone and muscle of a large bear. Hard-cast flat-nose bullets don’t expand; they drive deep and straight, reaching vital areas through tough barriers. For dangerous-game defense, that deep penetration is more valuable than expansion, which is why hard-cast is the standard bear-defense bullet.
